Can you post a full stack trace of this? Which log4j version are you
using? Neither the latest 1.2.x series or from trunk appear to match
up the line #'s.
Perhaps you are using an older 1.2, because in the latest 1.2 version
of SocketHubAppender that exception is not logged (there is a try/
catch block to trap ArrayIndexOutOfBoundsException, but I think
that's defending against logging done during the cleanup/close of the
appender).
cheers,

I have implemented the SocketHubAppender to send all the events to
Chainsaw.
Everything works fine (most times) but occasionally I get the
following
stack trace:
java.lang.ArrayIndexOutOfBoundsException: 0 >= 0
at java.util.Vector.removeElementAt(Vector.java:518)
at
org.apache.log4j.net.SocketHubAppender.append
(SocketHubAppender.java:208
)
etc...
It seems to crash at random and at different places in my application.
So my question is:
Is SocketHubAppender not thread safe?
Cheers,
Philip.
